FOR COAL PULVERIZATION IS THE MOST PREFERRED AND UTILIZED MILL. The capacity in #/hr. of the mill is calculated on the assumption that the coal hardness is 55 on the Hardgrove Grindability Index and has a moisture content of 8%. This would then produce and output based on 70% of the coal passing through a 200 mesh screen.
